Myinvention relatesto oice equipmen-t and more particularly to revolvingcard files and posting..tab1es.

The object of my invention is to provide a revolyfing. card le, whichcan be operated with very little effort.

i Another object of my invention is to provide a revolving card filewhich is in balance at all times.

A further object of my invention is to provide a revolving card fileenabling the operator to post any card in the fue without having tochange his position.

Astill further object of my invention is to provide a revolving card leenabling a second person to lhave access to the cards in the les fromthree sides of thetable, with which the file is connected, withoutinterfering with the work of the file operator.

Other-objects of my invention may appear in the following specificationdescribing my invention with reference to the accompanying drawingsillustrating a preferred embodiment of my invention.l

Itis, however, to be understood that my invention is not to be limitedor restricted to the exact construction and combination of partsdescribed in' the specification and shown in the drawings but that suchchanges and modifications can be made, which fall within the scope ofthe claims appended hereto. In the drawings Fig. l is a top plan view ofa posting table equipped with a revolving le according to my invention,the seat for a le operator being indicated in broken lines.

Fig. 2 is a front elevation of a posting table equipped with a revolvingfile forming the subjectmatter of my invention.

Fig. 3 isa top plan view of the frame work of the revolving disk in theposting table, the cover for the hub and center portion of this framework being shown in section, and

Fig. 4 is a sectional view taken on line 4--4 inFig. 3.

Referring now in detail to the drawings, a posting table Il)l isprovided in its top I I adjacent one of its ends with a circular cut-outI2.

Asupport member I 3 is fastened in any preferredconventional manner tothe frame of the posting table I and extends diametrically underneaththe circular cut-out I2.

An axle I4 has on its lower end a small circumferential flange I5 andunderneath this flange aloa'sey iiange I6, which is bolted tothesupport:

member i3 so that the axle I4 extends upwardly, ccncentrically with .thecircular cut-out I2.

A hollow cylindrical steel hub Il hasa thrust ball bearingV I8 in eachof its ends and is mounted rotatably on the axle Ill.

Four angle irons or arms I9 are rigidly connected with the hub Il,preferably bywelding, so that they extend radially therefrom at rightangles'to. each other. The length of these angle irons I9 is suchthat'they will not reach entirely to the edge ofthe circular cut-out I2in the table top I I, when they are attached to the hub I'l` and the hubis in position on the axle I4. The four angle irons I9 are arranged onthe hub Il, so that one o2. the legs of each'angle iron extendshorizontally and the other one downwardly and that the upper surfaces ofthe horizontally positioned legs .are located. in the same plane as thelower surface of the table top II.

Another set of fourangle irons 2li is firmly connected to the firstmentioned angle irons I9 by being welded on top of these angle irons, sothat the anglel irons 20 form a square, and the angle irons I@ extenddiagonally to this square, as clearly shown in Fig. 3. The` upwardlyextending legsof the angle irons 20 are located on 'the outside edge ofthe square.

A second square is formed by four shorter angle irons 2l, which are alsowelded onto the horizontally arranged legs of the diagonal angle ironsI9,lso that the shorter angle irons 2| extend parallel 'to the langleirons 20 forming the outer square and that the upwardly extending legsof these shorter angle irons 2l are located at the inner edge of theinner square. The horizontally arranged legs of each pair of anglesextending parallel to each other are' adapted to support a drawer 22 ofa filing cabinet as indicated in broken lines in Fig. 4.

Onto the under side of each parallel pair of angle irons 2U and 2I anangle iron 23 is welded so that the downwardly extending leg of each ofthese four angles extends radially to the hub I1 and at right angles tothe two angle irons to which it isattached. The inner end of each angleiron 23 is arranged flush with vertical leg of the adja cent shorterangle iron 2I and the outer end of said iron is located approximately atthe same distance from the axis of the hubk Il as the outer end ofthediagonal angle ironsl I9.

The portions of the horizontally arranged legs of the angle irons I9 and23a, which extend beyond the outer square angle irons 20 supportsections 24,01 plywood or otherl suitable material, abutting.

the upwardly extending legs of the outer square angle irons 20 andsnugly tting onto each other. On the outer edge each section 24 isarcuate so that the four sections together have a circular shape of asomewhat smaller radius than the circular cutout l2. The upper surfaceof the turn-table formed by these sectors 24 is located in the sameplane as the upper surface of the table -top Il. The latter and the turntable is preferably covered with a layer of Masonite or the like.

The plywood sectors 24 are fastened onto the horizontally arranged legsof the diagonal angle irons i9 and of the radial angleirons 23respectively by fiat head screws 25 or the like.

To reinforce the hub l1 four braces 26 are formed by angle ironsextending upwardly and inwardly from the back of the inner square angles2l to the hub Il as shown in Fig. 4.

A square box-shaped cover 2l rests on the inner square and protects thehub and center portion of the turn table frame.

The above description shows clearly that the revolving card fileaccording to my invention will be in balance at all times and can berotated with very little eifort since the entire construction issupported by two thrust ball bearings. The turn table accommodates fourdrawers of a filing case, and each card in any one of these four casesis easily accessible by the operator, without forcing him to change hisposition,

It is, furthermore, to be understood, that a second tum-table of thesame construction can be installed on the posting table, if so desired,to double the capacity of said table.
